@Kitonum and how to get information from the method? like, all the values of x and the corresponding value of the solution?

Thank you, my dear!

Yeah, you are right I just forgot the variables, after this post I have updated the code and replaced the SLB as you have mentioned.

I use the symbols \gamma, \beta, etc in my code, it is correct in the code which I used but when I have copied the code from maple to past here in this post, then it has been changed to this, otherwise, you are also right on your place.

Dear @Carl Love!

I'm very thankful to you for this kindness. I have needed this code of algorithm. It is very very useful to me in Mathematical Biology.
